' tube.

In the drawings the housing or casing is cylindrical and comprises two half-cylindric sections a and a, which in the present instance are provided with abutting flanges b and h, by means of which the said two sections are secured together. tion a of the casing is provided with an integral base having laterally-proj ectingfianges c, on which the casing rests. Suitable bearings (Z are provided in the casing at each side for supporting a hollow shaft e, which extends centrally through the casing and projects 011 the exterior thereof at either side A pulley f is secured on one end of the hollow shaft on the exterior of the casing, and

. the other end of said shaft on its interior is provided with a shoulder g, and from said shoulder to its end the shaft is provided with internal screw-threads h. A bushing z' fits into one end of the shaft 0 and is provided with exterior screw-threads which engage the threads 7L on the interior of said shaft. The

bushing i is also provided with a central smooth bore, through which a stationary the coils Z.

The lower sec-.

tube j passes into the end of the hollow shaft 0. The end of this tubej is provided with a and one end of a coiled tube Z is secured to the said shaft is and is coiled therefrom, each succeeding coil Z having an increased side as compared with the inner coil nearest the said shaft. Theoutermostorlargestcoilofthetube is provided with an abrupt bend Z and the extreme end of said tube is turned backward U-shaped and in a direction parallel with This abrupt bend Z in the end of the out-coil forms an abutment against which the steam or air strikes immediately before it is discharged at the turned-back end Z and aids in driving the tube forward. An outlet-pipe m in the bottom of the casing serves as an exhaust from the casing. It will be seen that the steam or air (whichever may be used) passes through the coiled tube in the same direction that the tube turns, as indicated by darts, and that this'course is maintained until it strikes the abutment formed by the abrupt bend 1 where the course of the steam or air is changed and directly reversed. This abrupt change in the course of the steam or air increases the speed and force of the revolution of the motor.

I am aware that it has heretofore been proposed to provide rotary motors with metal wheels having scroll-shaped passage-ways; but as far as I am aware I am the first to provide a coiled tube having one end of its spiral connected to and in communication with a hollow shaft and the outmost end of the spiral being free and having a U shaped bend near its discharge end, whereby to abruptly reverse the course of the steam or'air.

Having thus fully described my invention, coil provided with an abrupt bend turned .0 what I claim as new, and desire to secure by backward U shape and having a discharge- Letters Patent, is outlet beyond said bend.
